I have a friend who is 73 and still says "barfroom" for bathroom, and "pacific" for specific, amongst many other things. She mispronounced my son-in-law's name and continued to do so, which I thought was rude, even after she had been corrected. I find it annoying and I'm sure my son-in-law did, too, although he was too polite to say. It was not even a difficult name to pronounce.
Some people eh! What can you do? 
Engagement Party and then Hen Party
Why can't I wear this to a wedding?
How can I stop people from 'helping' ?
Strawberry plants- what is the problem with them, can anyone advise, please?
. So I have backed off.
